Response of soil biological properties and bacterial diversity to different levels of nitrogen application in sugarcane fields.

ABSTRACT: To select an eco-friendly nitrogen (N) application level for sugarcane production, soil fertility and soil bacterial diversity under different nitrogen application levels were analyzed. Four levels of urea applications were high Nitrogen (H, 964 kg ha^-1), medium Nitrogen (M, 482 kg ha^-1), low Nitrogen (L, 96 kg ha^-1) and no Nitrogen (CK, 0 kg ha^-1) treatments, respectively. The results showed that the soil microbial biomass carbon and phosphorus were altered significantly by CK and L treatments. Moreover, the indexes of soil bacterial richness and diversity in the sugarcane field could be significantly improved by L. At the genus level, SC-I-84, Mycobacterium, Micropepsaceae, Saccharimonadales, Subgroup_2 and Acetobacteraceae were the unique domi
